I tried this a few months ago, it didn't work, and I haven't had LWP's since. I put my original LiveWallpapers.apk back in /system/app and have changed the permissions to rw,r,r and it still won't install. When I go to install it with Root Explorer, it asks if I want to replace the application. I think I may know why.
In Settings-->Applications, there are 2 LWP apps, LiveWallpapers, and Android Live Wallpapers. I think the latter may be an auto-updater for the LWP app, like the updater for the market app. It shows that it has data and cache stored, but the buttons to clear them are grayed out. I feel pretty confident that if I could clear these, or delete the app, I could have LWP's again. Anybody know where the data and cache for this would be stored so I can delete them manually?
